Precautions when using and maintaining the engine water pump

during correct installation, the gear of the gear driven water pump should be closely combined with the transmission gear, and the belt driven water pump should ensure that the coaxiality of the water pump shaft and the pulley is within the specified range, so as to prevent the engine from shaking the water pump due to increased speed or load and aggravate wear

correctly adjust the tightness of the whole belt. The fan belt cannot be adjusted too tight, otherwise the load of the water pump bearing will be increased. If it is driven by more than two belts, it is necessary to ensure that the new and old, length and tightness of several belts are consistent, so as to prevent premature damage of the water pump due to uneven tension of each belt

fill lubricating oil in time. Fill lubricating oil into the water pump bearing in time according to the provisions in the manual. Filling lubricating oil is called yield point or physical yield strength. At this time, the display may not display 0.0 (± 1.0kn is the allowable value); The quantity should not be too much or too little to prevent premature damage of the bearing

do not block the overflow hole. There is a overflow hole at the pump shaft, passing through 2 Increase the reproducibility of the test overflow hole to observe whether the water pump leaks. If the overflow hole is blocked, the water leaked by the water pump will enter the bearing and affect the lubrication, causing premature damage to the bearing

do not knock hard during disassembly and assembly. When repairing the water pump, use special tools to disassemble the belt pulley, inner bearing of the water pump and other main parts. If the pump is hard knocked during installation, it is easy to cause bending and deformation of the pump bearing, thread slippage or damage at the end of the pump shaft. In addition, because the impeller fits closely with the pump shaft, it is generally not disassembled unless necessary

timely remove the scale in the water pump. Excessive accumulation of scale in the water pump will weaken the water pumping capacity of the water pump. At the same time, the scale will also corrode the components in the water pump, which is easy to cause premature damage of the water pump. (end)
